I have known plenty of people who act and do exactly as you have described, and I have no issues with that whatsoever. In fact I am certain of my child were missing I would look like complete crap. My biggest problem is that their stories have changed sooooooo many times. Ok, fine Shaylyns crib is in the living room, well the issue isn't that it's in the living room, it's that they had people in and out of that house constantly that evening and at some point something happened to an innocent 14 month old baby.
1)Did Shaylyn throw a fit and Justin get rough with her and they are all covering?
2)Did they medicate her to get her to go to sleep because the constant noise was keeping her up, and ended up over medicating her?
3)Or did Kyle come back and take her and something happen?
We don't yet know, we will soon enough but at the end of the day there is a cover up going on, and I firmly believe LE is doing a great job this far. Just my take on it from the outside looking in.
